St John's Wort (Hypericum perforatum) Oil on Immune Response, Growth Performance and Bacterial Resistance Against Lactococcus garvieae Pathogen in Rainbow Trout (Oncorhynchus mykiss)

Journal of Fish Diseases, EarlyView.
ABSTRACT In this study, we investigated the immunomodulatory effects of St. John's Wort (Hypericum perforatum) oil on the growth performance, immune responses and resistance against Lactococcus garvieae in rainbow trout (Oncorhynchus mykiss). The plant oil was incorporated into feeds at concentrations of 1, 3, and 5 g kg−1, designated as K1, K3, and K5,

Molecular insights into electroreceptor ribbon synapses from differential gene expression in sturgeon lateral line organs

Journal of Anatomy, EarlyView.
The expression of various genes involved in synapse development, stability and/or function was studied in developing mechanosensory neuromasts and electrosensory ampullary organs in sterlet sturgeon. Most were shared, including Slc17a8, Slc1a3 and Nrxn3, but Cbln18 was neuromast‐restricted and Tulp1 was ampullary organ‐restricted.

Performance and Health Status of Juvenile Largemouth Bass (Micropterus nigricans) Fed Inclusions of Enzyme‐Treated and Low‐Oligosaccharide Soy Proteins

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Plant‐based proteins, such as soybean meal (SBM), have shown promising results in cultured species but also present challenges due to their nutrient composition and inherent antinutritional factors. This study investigated how the replacement of solvent‐extracted SBM with low oligosaccharide soybean meal (LSBM) or enzyme‐treated soybean meal ...

A Preliminary Study on the Determination of Triploidy by Chromosome Analysis at the Different Stages of Development in Rainbow Trout, Oncorhynchus mykiss

Marine Science and Technology Bulletin, 2013
There are several methods for ploidy determination of fish, those have been developed by many researchers until to date. For these methods, the cost and the applicability of each stage of fish development are very important.
